provide a fore-truck for such Scrapers` whereby certain objections areovercome and advantages gained, as hereinafter fully set forth.

It is well known that two-wheel dumping Scrapers are advantageous inmany kinds of cutting and filling in road work, particularly in beingmore conveniently handled'in many situations. These kinds off-Scrapers,however, are objectionable to a high degree in one respect, to wit, inthat-they. throw an excess amount of neck strain upon Vthe e draftanimals, causing serious cases of` sore neck, and also produce excessivetongue.

slashing, making them very hard upon the draft animals. theseobjections, four wheel Scrapersv are used, but ythese Scrapers, inadditionto being much more costly and complex in construction, arevnotas advantageous Vto use in many cases as two-wheel Scrapers.

The object of my invention is to provide a fore-truck which may beapplied to any ordinary type of two-wheelscraper with little or nochanges in the construction of the scraper, and which will serve to giveproper ,support to the draft tongue as well as cony trol thereof, so asto relieve the draft ani- Vmals both froml .neck strain and side slash-.n.of the arched axle, which 1s secured thereto me. Y

still further object of the invention is to provide a fore-truckattachment for twowheel scrapers which embodies means whereby the wholeor greater portion of the weight of the tongue may be sustained from thebody of the implement and the tongue controlled, rendering the implementmuch easier upon the draft animals. l

With these and other obj ects in view, the invention consists of thefeatures of construction, combination and arrangement of parts hereinfully described and claimed,

reference being had to the 'accompanying' drawings in which In anattempt to remedy- Figure lis aside elevation showing the application ofmy fore-truck to a two-wheel scraper of ordinary construction. Fig. 2 isa top plan viewof the same. Fig. 3 is a vertical `longitudinal sectionon line `3-3 of Fig. 2. t is a vertical transverse lsection on line/ifaof Fig. 2. Fig., is a perspective yiew of the truck detached.

Referring to the drawings, 1 designates a two-wheelscraper of anyordinary construction, provided with :the usual dumping dirt pan 2, anarched axle 3, supporting wheels 1, c and .a vframe yincluding forwardlyextending side pieces 5 connected at the front by -a cross .bar 6. Tothis cross` bar is usually 'bolted the scraper tongue, whichAextendsbetween and is also bolted tothe forward parallel portions ofthe-frame-arm'. It will of course be understood that in this type ofimplement the load weight falls Vupon theYU Y tongue sustainedv by thedraft animals, and that owing to the freedom of motion ofthe scraper `inpassing over rough ground,- etc.,

the animals arev subjectednot only to neel;

Yso

strain from the weight of the load, but also to slashing from sidewisemovement of the I tongue. s v Y. Y In carrying my invention intopractice 'IV provide a fore-truck comprising an arched axle 7 on theends of which are journaled supporting wheels 8. The centralpart of. 'ithis arched axle is fastened to the rear end of a main tongue 9, andsaid parts are connected and Vreinforced by braces 10., The

wear lplate 11is applied Vtothe upper rear c surface of the tongue and1s arranged be'- neath a draft iron 12, which is bolted therewith` totheI tongue. plate 11 projects beyondV the end of the tongue 9 anddisposed beneath this projectrllhe rear end of thevl ing end .of theplate is the central lportion 2 by a suitable clip or clamping device13. The front and rear ends of the draft iron are bent upward to formclevises 1a and 15 apertured for the passage ofpivot bolts 16 and 17.Tor the clevis 14 may be attached to be attached to the scraper, thestub tongue being employed to take the place of the usual tongue of thescraper. This stub tongue is attached to the frame arms of the scraperand to the cross bar 6 of said scraper by sets of bolts 23Iand 24, andmay be reinforced from the cross bar by a brace 25, the constructionthus'being such that the front portion of the scraper, and the weight ofthe load carriedl thereby, will fall upon the supporting wheels 8 of thefore-truck, thus relieving such weight of the load from. the neck of thedraft animals. VIt will be evident that'the implement may be steered tothe right or `left by turning the truck'on the pivot 17 between thefront and rear y sections thereof, thewheels 8 turning under therstubtongue, allowing the devicel as a whole to be steered land turned withease and facility. Y Furthermore, thefront truck opposes a resistanceagainst sidewise deflection, preventing sidewise movementof the mainVdraft tongue, and Ythus also relievingl the draft animals of: sideslashing.'V To further assist inV relievingthe draft animals of* neckweight and strain, and whatever vlittle side slashing might otherwiseexist, I provide a supporting and controlling` connection between `thefront pivoted section of the truck and the rear rigid portionthereof,

chain or its equivalent 26, which is adjust'- ably connected. at litsforward end to an adjustable clip or` fastener 27 on the main' tongueand thence extends rearwardly and desired elevation,\the spring28'yieldingl as Copies'fof fthispatent may obtainedffor required toprevent the tongue from thresh ing vertically, Vand that the height towhich the maintongue-maybe adjusted, as well as the resistanceofthe'Spring, may be regu lated by connectingldifferent lengths ofthechain with the hook orclip 27. Thisfcon-f trolling connection,therefore, will not only support the rnain'tongue` and assist the trucklproper in preventing the weight of the-load from being thrown. upon; thenecks ofthe v draft animals, but willi. further serveAW to Y diminishwhatever tendency there may-be to a sidewise motionbr lateral threshingofthe Y tongue. y

From the foregoing'description, taken; in Y connection withthe drawings,the construction and mode of use of my improved fore-- truck willbereadilylunderstood,and it will Abe seen that the invention provides adevice of this character ,whichfmay be applied to any ordinaryrtypel ofVtwo-wheel scraper` 70 with little or no changefin the construction ofthe latter, 'and that it will support :the

scraper and the weightjoffthe load and pro- Y vide an implement which,in addition 1t`o'1 "t possessing all `fthe advantages oftheordii naryscraper, will overcome all of ithefdi's.-

advantages stated ina readyand convenienti vmanner,v Yor the portionattached directly to 'the scraper. This connection comprises a link Afore-truck for two-wheelscrapers com prising a two-wheeled frame, adraftftongue carried vby said. frame,- apivotallymounted f stubtonguefadapted lto be fastened tothe;
